stress = Force /Area of contact => 20/(pi*0.5*0.5) N/mm^2

strain = delta(l)/l = > 1/3

Young’s mudulus = stress/strain

Hence,

Y = 20*3/(pi*0.5*0.5) = > 76.43312 N/mm^2

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
